[0002] Wheelchairs are very important to the lives of people who are inconvenient to walk. A good wheelchair can bring a lot of fun to people who are inconvenient to walk. Existing wheelchairs generally do not have braking systems, and a small amount of wheelchairs are provided with braking systems. The braking system generally does not brake automatically, which cannot guarantee the safety of people when the wheelchair moves too fast, and there is no auxiliary braking system such as ABS when braking, and it is very expensive to install auxiliary braking systems such as ABS on the wheelchair

Embodiment Construction
[0018] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0019] Such as Figure 1-Figure 3 As shown, the technical solution adopted by the present invention to solve its technical problems is: a wheelchair with automatic braking function, comprising a main body and a wheel 9, a seat 6, an armrest 1, a battery, a braking mechanism and a speed measuring mechanism arranged on the main body 7. The wheels 9 and the armrest 1 are both arranged on the seat 6;
[0020] The brake mechanism includes a brake pad 8, a brake caliper 10, a piston 11, a hydraulic pipe 2, a brake master cylinder 3, a pole 5, a traction wire, a reel and a motor 4, and the brake pad 8 is coaxially fixed with the wheel 9, The brake caliper 10 is pro...

The invention relates to a wheelchair having an automatic brake function. The wheelchair comprises a main body as well as wheels, a seat, armrests, a storage battery, brake mechanisms and speed-measuring mechanisms, wherein each brake mechanism comprises a brake sheet, a brake caliper, a piston, a hydraulic pipe, a brake master cylinder, a supporting rod, a pull wire, a wire coil and a motor; and each speed-measuring mechanism comprises a first connecting rod, a second connecting rod, a spring, an iron block and an electromagnet. The wheelchair having the automatic brake function is elaborate in design and reasonable in structure; by squeezing the brake master cylinders by virtue of the supporting rods, friction brake is achieved between the pistons and the brake sheets; in the case that the wheelchair moves too fast, the motors can be automatically turned on by virtue of the speed-measuring mechanisms so as to draw the supporting rods to achieve brake; and in order to prevent falling which easily occurs in the case of emergency brake, the iron blocks can be adsorbed by virtue of the electromagnets, so that brakes are loosened by virtue of the speed-measuring mechanisms, and subsequently, the speed of the wheelchair is slowly reduced.
